"Utility to recover Windows passwords."
Have you forgotten the password to your Windows system? Then this is a big problem ... unless you have a program like OphCrack. OphCrack is a tool that uses Rainbow tables to recover forgotten passwords for Windows.
You can use OphCrack in two ways: run it from the operating system, or run it from a different partition or hard drive. The program`s effectiveness has been tested at 99% of cases, always with alphanumeric passwords. You can get out of that fix.
